Completion pneumonectomy for lung metastases: is it justified?
OBJECTIVE
To evaluate the postoperative outcome and long-term results of patients who underwent iterative and extended pulmonary resection leading to completion pneumonectomy for pulmonary metastases.


METHODS
From January 1985 to December 1995, 12 patients (mean age 45 years) underwent completion pneumonectomy for pulmonary metastases. These patients represent 1.5% of all pulmonary metastases operated on. There were 5 sarcoma and 7 carcinoma patients. Before completion pneumonectomy, 8 patients had only one pulmonary resection (wedge resection, 2; segmentectomy, 2; lobectomy, 4), 3 patients had two operations and finally, 1 patient had multiple bilateral wedge resections and 1 lobectomy. The median interval time between the last pulmonary resection and completion pneumonectomy was 13.5 months (range 1-24 months).


RESULTS
There were 10 left and two right completion pneumonectomies. Three patients had an extended resection (1 carina; 1 chest wall; 1 pleuropneumonectomy). Intrapericardial dissection was used in 3 patients. Two patients died within 30 days of the operation: 1 died of postoperative complications (8.3%) whereas the other died of rapidly evolving metastatic disease. The remaining 10 patients had an uneventful postoperative course. Only 1 patient is still alive and free of disease 69 months after completion pneumonectomy. One patient is alive with disease, another was lost to follow-up; 9 patients died of metastatic disease. The median survival time after completion pneumonectomy was 6 months (range 0-69 months). The estimated 5-year probability of survival was 10% (95% CI: 2-40%).


CONCLUSIONS
Indications for both iterative and extended pulmonary resection for PM may be discussed only in highly young selected patients; the extremely poor outcome of our subgroup of patients should lead to even more restrictive indications of CP for pulmonary metastatic disease.
